为实现自然条件下棉花叶片的精准分割,提出一种粒子群(Particle swarm optimization,PSO)优化算法和K-means聚类算法混合的棉花叶片图像分割方法。
本算法将棉花叶片图像在RGB颜色空间模式下采用二维卷积滤波进行去噪预处理,并将预处理后的彩色图像从RGB转换到目标与背景差异性最大的Q分量、超G分量、a*分量;
随后在K均值聚类的一维数据空间中,利用PSO算法向全局像素解的子空间搜寻,通过迭代搜寻得到全局最优解,确定最佳聚类中心点,改善K均值聚类的收敛效果;
最后,对像素进行聚类划分,从而得到棉花叶片分割结果。
按照不同天气条件和不同背景采集了1 200幅棉花叶片样本图像,对本研究算法进行测试。
试验结果表明:该算法对于晴天、阴天和雨天图像中目标(棉花叶片)分割准确率分别达到92.39%、93.55%、88.09%,总体平均分割精度为91.34%,并与传统K均值算法比较,总体平均分割精度提高了5.41%。
分割结果表明,本研究算法能够对3种天气条件(晴天、阴天、雨天)与4种复杂背景(白地膜、黑地膜、秸秆、土壤)特征混合的棉花叶片图像实现准确分割,为棉花叶片的特征提取与病虫害识别等后续处理提供支持。

1stOpt一套数学优化分析综合工具软件包。
在非线性回归,曲线拟合,非线性复杂模型参数估算求解,线性/非线性规划等领域傲视群雄,首屈一指,居世界领先地位。
其计算核心是基于七维高科有限公司科研人员十数年的研究成果【通用全局优化算法】(UniversalGlobalOptimization-UGO),该算法之最大特点是克服了当今世界上在优化计算领域中使用迭代法必须给出合适初始值的难题,即用户勿需给出参数初始值,而由1stOpt随机给出,通过其独特的全局优化算法,最终找出最优解。
---------------------------------------------以非线性回归为例,目前世界上在该领域最有名的软件包诸如Matlab,OriginPro,SAS,SPSS,DataFit,GraphPad等,均需用户提供适当的参数初始值以便计算能够收敛并找到最优解。
如果设定的参数初始值不当则计算难以收敛,其结果是无法求得正确结果。
而在实际应用当中,对大多数用户来说,给出(猜出)恰当的初始值是件相当困难的事,特别是在参数量较多的情况下,更无异于是场噩梦。
而1stOpt凭借其超强的寻优,容错能力,在大多数情况下(>90%),从任一随机初始值开始,都能求得正确结果。

在日常工作中,钉钉打卡成了我生活中不可或缺的一部分。然而,有时候这个看似简单的任务却给我带来了不少烦恼。 每天早晚,我总是得牢记打开钉钉应用,点击"工作台",再找到"考勤打卡"进行签到。有时候因为工作忙碌,会忘记打卡,导致考勤异常,影响当月的工作评价。而且,由于我使用的是苹果手机,有时候系统更新后,钉钉的某些功能会出现异常,使得打卡变得更加麻烦。 另外,我的家人使用的是安卓手机,他们也经常抱怨钉钉打卡的繁琐。尤其是对于那些不太熟悉手机操作的长辈来说,每次打卡都是一次挑战。他们总是担心自己会操作失误,导致打卡失败。 为了解决这些烦恼,我开始思考是否可以通过编写一个全自动化脚本来实现钉钉打卡。经过一段时间的摸索和学习,我终于成功编写出了一个适用于苹果和安卓系统的钉钉打卡脚本。
